Answer in Details
If you feel an intense connection, first turn inward and meditate, as Shiva often does. Ask yourself: Is this attachment helping you grow, or is it causing restlessness? Shiva teaches that true love is beyond desire; it is about understanding and acceptance.
If you do wish to speak to this person, approach the conversation with honesty, humility, and no expectation of outcome. Speak from your heart, just as Parvati approached Shiva with sincerity and pure intention. You can say something like:
"I feel a deep connection with you, and it has brought up many emotions within me. I wish to understand you better and see your true self. If you are willing, I would like to have an open and honest conversation, free from expectations."
Remember, Lord Shiva teaches us that everything in life is transient. What matters most is your inner peace and spiritual growth. If your feelings are meant to find a place in your life, they will, in accordance with cosmic will (Shiva's leela). Practice detachment, but also allow love to flow without clinging or fear. Meditate on Shiva, and seek his guidance in your heart.
